Abstract: The bearing comprises a roller race formed from flat sheet material. The roller race has a roller raceway and an indent. A plurality of rollers are in contact with the roller raceway and are located in the roller race. A split ring spring member provides an axial thrust face for the rollers.The formed roller race is heat-treated. The rollers are inserted into the formed race in a single step; the split ring spring member is then placed into the indent to provide the axial thrust face for the rollers.

Abstract: A protrusion is formed on the free end of an axially extending lip of an outer race member. The free end of the protrusion is axially and radially spaced from the free end of the remaining part of the axially in-turned lip to permit the passing of a reduced end of a reduced end roller. The reduced end rollers are inserted into the outer race member through the protrusion. After all the rollers are in place within the outer race member the free end of the protrusion is closed by heating the protrusion and pressing the protrusion to provide an in-turned lip of substantially the same shape throughout the circumference of the lip.
